Birefringent Fiber Loop to Improve Directly Modulated Laser Diode Pulses

2005 Pacific Rim Conference on Lasers & Electro-Optics, 2006
We describe the use of a birefringent-fiber-loop (BFL) to improve the signal from a 10Gb/s directly modulated DFB laser. The BFL reduces amplitude transients, frequency chirp and pattern dependence in the directly modulated signal.

Intensity measurement based temperature-independent strain sensor using a highly birefringent photonic crystal fiber loop mirror

Optics Communications, 2010
A fiber-optic strain sensor is demonstrated by using a short length of highly birefringent photonic crystal fiber (HiBi-PCF) as the sensing element inserted in a fiber loop mirror (FLM).

Liquid-level sensor with a high-birefringence-fiber loop mirror

Applied Optics, 2006
A novel liquid-level sensor with a high-birefringence-fiber loop mirror (HBFLM) based on a uniform-strength cantilever beam (UCB) is proposed and demonstrated. Part of the high-birefringence fiber is pasted onto the central surface of the UCB. A hollow suspending pole is utilized to apply force at the end of the beam.

Nonlinear optical loop mirror with low birefringence twisted fiber in the loop

Optics Communications, 1998
Abstract The fiber loop mirror constructed from low-birefringence twisted fiber was numerically examined. Nonlinear ellipse rotation effect has been taken into account. Nonlinear switching has been found for the balanced configuration with a 0.5/0.5 coupler.

Multiwavelength fiber laser based on a high-birefringence fiber loop mirror

Laser Physics Letters, 2006
In this letter, we propose a novel multiwavelength fiber laser based on fiber loop mirror formed by a high-birefringence fiber, a polarisation controller, and a 3 dB directional coupler. By setting the polarisation controller as half-wave-plate, the fiber loop mirror acts as a polarisation-independent wavelength filter; Erbium-doped fiber (EDF ...

Temperature compensation for high-birefringence fiber loop mirror

SPIE Proceedings, 2005
We propose a novel temperature compensation method that HBF is mounted on a piece of organic glass. It can lessen its temperature sensitivity to 0.059 nm/K, which are two orders of magnitude lower than that of an uncompensated HBF loop mirror. It is feasible that HBF loop mirror packaged with a large thermal-expansion material is insensitive to ambient

A hydrophone based on high-birefringence fiber loop mirror

SPIE Proceedings, 2010
A new type of hydrophone based on high-birefringence fiber loop mirror (HiBi-FLM) is proposed and demonstrated. The sensing part is a section of high-birefringence fiber wound onto a hollow metal cylinder fiber. A narrow band light source is used and the detection is done by measurement of light intensity.
